But why?

Illustration Friday Night was a group art project that ran for over a year. It was created by Senor Prozac as a response to images being censored and banned on Illustration Friday.
The plan for IFN was to give artists an alternative platform for high-quality work that wasn't just about kitty-cats and cuddly ducklings.
Many of the 2000 images sumbmitted to the site provided a vibrant foil and counterbalance to IF-cutesiness.
It was nominated as a Blog of Note by Blogger in September 2007. Like a lot of things on the internet (and life in general), it ran out of steam in 2008.
